The Lightning SE features triple butted Columbus Spirit steel
frame tubing (see tech info from Columbus below). Each frame
is hand tig welded and all aspects of the alignment are checked
before any frame leaves the factory. The fork features carbon
fiber blades, with an aluminum steerer.

There are two critical aspects of frame design- cockpit design
(rider fit- where the rider connects to the bike and where these
points are in relation to each other) and steering/handling. I
design the frames here, in-house, to ensure the desired  
characteristics. The seat tube angle, top tube length and stem
height and length are the key elements to consider for correct
rider fit. Then, for handling, stability and agility are both
considered- too stable and the steering is heavy; too quick and
the bike is twitchy, more difficult to control, especially at slower
speeds. I designed the
Lightning SE using traditional road
racing geometry with tweaks for  fixed gear riding (for more
info on Wabi's
frame and wheel design philosophies, click here).

Samples are then built for stress testing on a machine. Wabi
frames are built to the most rigid standard, the EN, the current
European standard. This is your assurance of the quality and
structural integrity of each Wabi Cycles frame.

The
Lightning SE is not just another steel frame- the quality of
tubing, design and manufacturing combine to create the
traditional ride that the best steel frames are known for. The
Wabi
Lightning SE will amaze you, both with its beautiful
workmanship and plush ride.

*Traditional steel frames use 25.4mm diameter TT, 28.6mm ST
and DT. The spirit tubes are 31.7 TT and 38.0 DT. ST remains
the same.

Steel is steel is steel, right? No. The type of tubing matters. Click here to connect to an
article on steel tubing. It can be confusing- hopefully this article will help fill in some gaps.

Dimensions in mm            
A word on fit. There is no one way to nail
correct fit on the first try. If you've been
riding a long time, you probably know what
you need, from the dimensions on an
existing bike (see our
fit guide page for
more info).

One word of caution about positioning
adjustments- general wisdom is to not
radically change seat height, to avoid knee
problems. This is more important the more
you ride. So, try to get as close to right as
you can initially on seat height and then
modify by 3 or 4mm as needed.

I've had many years of experience in fitting
people to bicycles, both in person and long
distance, so if you have any questions as to
what frame size you should get, or other
dimensional questions,
contact me and I'll
be glad to help you.
